Square root in 3 seconds - math trick 

how to work our uneven sqarue roots like 32

Teachers be like: "It'S NoT My WaY So It'S FaLsE!"

This is the kind of thing that makes me love math, it's a shame that most teachers make it boring.

Thank you, sir!!! At 30, I am re-teaching myself basic math, and I am learning so much more than I ever did at school from people like you.

I've NEVER been able to do square root.... at the age of 50 I can now say I can, smiling from ear to ear! Thank you so much..... there should be maths teachers everywhere like you!!!!! 💗

The fact that I learned this in like 30 seconds but can't learn it in school in 3 hours is amazing

he sounds like the voice in the airplane being like “wE WiLl rEaCh cAnAdA iN 12 hOuRs”

Mother was a teacher. She would not teach her kids in school, but she loved math and would teach me all the neat math ‘tricks’ at home. Made me love math too. Great video.

cool tip, thank you. As someone who has forgotten most of my secondary school math, and would just google how to solve the occasional business math problem, this is a very helpful trick even if it doesn't work for 100% of cases. 'Good enough' is good enough if you're in the everyday world and are not a scientist/engineer.

When my son watched this video. His friends were suprised that he can solve a big square root number very quick. Thank you very much

Whenever I come across these vids I'm always astounded by how simple and logical the methods used are and am dumbfounded as to why I was never taught this in school, good stuff.

I just retired from a long career as a math teacher. I learned many mental math tricks as a girl, and I love all of yours. I used to show your videos to my students if we had a few minutes left at the end of a period. Brilliant!!

I have searched all over the web and so far, your explanation and pace is so easy to understand. Thank you soooo much! 🤗

You taught me what my school can’t teach me in all these years. Thanks.

GDAY passengers! We have arrived in Melbourne, the weather is quite humid today with a bit of rain tonight. Hope you enjoy your stay and remember that the square root of 9 is 3.

bro thank you so much for this, I am literally moving up to high school in a few weeks and things like these I am sure will pop up everywhere.

I learnt more from you brother than all the teachers I have met in all my life of schooling.

why am i only hearing this now. Im almost graduating high school. wtf.

Bro I realized I didn’t know how to find the square root I tried reading a ton of stuff till the point I started crying from feeling dumb I watched this for five minutes and learned something THANK YOU

A quick way of finding the two matching digits in the squares of 1-9 is to only check the squares of 1-5. The other "matching" number will always be the one that when added to the first matching number, will add to 10. Example: if I had the number 1746, I would know that my last digit could be either 4 (4x4 = 1 *6* ), or 6 (6 + *4* = 10)

I stared at the number thinking 'How in the world would I know the square root of that?!' And then as soon as you started explaining, I remembered I learnt this last year. I'm so glad I found this video to refresh my memories because otherwise, I would never have been able to

i’m not looking at games or speed runs or the usual business id search, i’m watching how to do math equations. that’s pretty powerful man, good on you

I’ve spent my entire life trying to learn maths. And I still try. I taught maths but very special needs and my way of doing it was through fun. Games, etc. Number bonds. But at 63 I still try to challenge myself. For the young people I taught it was always about being inventive in my approach. But for me own development these tips are brilliant thank you

Everyone's a gangster till Boris Johnson starts teaching maths 🥶

I put off watching this video for 3 or 4 years but man am I glad I watched it. So useful

When you watch math videos because of the Corona Virus

Nowadays teacher gotta be like “no work no credit” *triggered*

This shows how a youtube math teacher is better & interesting math teacher than your school math teacher. Thanks

Wow! I absolutely HATED math in high school...now at age 75 I finally learned how to find square roots of numbers!! Thank you! It's actually fun! Sort of like knowing the 'secret' behind the magic trick! This is something my teachers never knew how to do.

i said 24 randomly and i think i'm the next physic twin

Why are there so many comments hating on your voice? Your voice is awesome! Australian?

Just for your own knowledge, I'm at the University in Belgium, and that's not right when you said at the beginning that a square root have to be specified as positive and negative, a square root is always positive, for a simple exemple, take the square root fonction (f(x) = sqrt x) and you will see that the answer is always positive, the trick is that : -when you say "wich number squared is equal to something", the answer is positive AND negative -but when you say "what is the square root of something", the answer MUST BE positive The difference is very low, but is there, and can't be unknown, but regardless of that very little and common mistake, the video is really great 👌 (sorry if my English is bad or if you had understood my com like angry or bad written, it's because I speak French, and don't really have the habits to speak English 😉

Teachers make it more complex. But people like you try to make out the easiest way to explain it.

Me: *seeing number 6* My mind: *"2 and 4"* Me: *"24"* And the answer showed up as 24. I'm an idiotic genius.

Thanks Chris Hemsworth, I'm remembering this for the rest of my life.

This video was really helpful!! Usually when I'm trying to find square roots I usually use the long division method, but that's really time consuming. These steps were easy to understand and the method's quick to do. Thanks for the great video! :)

I had a hard time understanding your explanation because english is not my first language but I watched it over and over again until I finally understand it thank you 😊

- "Hey Siri, whats the square root of 576 ?" - ”24” One second. I won.

In high school, my listening is very good and I can’t understand my match teacher when it comes to square root. Now, I am in my mid 40’s and I have a slower mind but I understood everything you’ve explained and it was a piece of cake.

This will be so useful for the sat and act. They should teach us this in school

That’s about how long it takes to put it in my calculator

This man, legend, he starts his lesson with a G' day.

Thanks this is gonna boost me through algebra.

Someone else tried to teach this on their YT channel and failed miserably. You DID IT!!!!

was expecting a 3 second video, still watched the entire thing great video

... and make sure you have a safe flight

Tysm you're videos are the best I learned on how to find the square root of 6084 which is 78 In under 30 seconds! If this was taught in school It would take 5 hours

Thank you for teaching me square roots in 9 minutes and 45 seconds

I am sleeping in math class but I'm watching this in my spare time.... yea seems fair to me

Alternative option: Memorize them all

I’m 75, I went to parochial school for 12 years. I felt I received a better than average education. In high school, math was difficult for me. I could do much of it in my head, but I had a rough time with equations. Some teachers…..nuns…..couldn’t teach for anything. Basically robots. I have a dear friend who was a nun for 20 years, she taught history and math. She only had a high school education. While that in itself isn’t bad, I wonder if she was really qualified to teach? She said many of the younger nuns didn’t have degrees. Some were highly educated, but didn’t have a clue how to teach. I did eventually end up with a math degree in my twenties but it wasn’t because of how I was taught in high school. These videos are amazing, I wish we had them when I was in school.

Video title: How to calculate square root in 3 seconds Video length in one problem: 5 minutes

Grandpa- back in my day we used to do square root like... Me- done in 3 seconds Grandpa- well my time has come

This is useful in specific situations. But you don't always know just by looking at a number that it is a perfect square.

Nah, this guy taught me more useful stuff than my school did in 14, years

❤❤❤❤❤THANK YOU SO MUCH I WAS STRUGGLING WITH MY MATH HOMEWORK JUST TRAIL AND ERRORING AND I FOUND THIS. TYSM🎉🎉🎉🎉

Quarantine got me so psycho that i watch math videos at home when there isn't even a test or an online study goin on.

This is a perfect example of a math trick versus math knowledge. What I like about this is that it generates interest in square roots! I think this could be push farther by thinking about extention questions like "What if we did not have a perfect square? What would happen?" We can see that if our number ended in a digit other than 1,4,5,6, or 9 then we would not have a perfect square. This is because when we multiply multi-digit numbers we start in the ones place which for perfect squares has to be the same number. This is also why we only need to know the squares for 1-9.

i didn't get much sleep last night, put this on today to learn the things i didn't understand from the textbook and your voice was so soothing it put me to sleep immediately and i woke up to an ad on another video lol (coming back to it later when i'm not so tired to actually learn what you're saying)

Never thought I would learn something so useful from a foreigner teacher Thnx sir you helped a lot .

Why does he sound like Bob Ross of math equations, sounds so calm and in order

He sounds like the voice of the guy using the mic in an airplane!

I enjoy the heck out of these tricks!

a 10 minute video to show how to find square root in 3 seconds insane🔥🔥🔥🔥🔥

I wish all the teachers explain like this every student would have ATLEAST 80% out of 100 in math

I guess me and 5+ million other people want to know this trick in maths lol

I am 36 now...i was awful at math in school and I didnt understand why. It made absolutely no sense to me these formulas. They used to make my head spin and i was SOOO lost that I was afraid of asking questions . even if I did ask questions...the teachers could never help me understand so I ended up shutting up and failing all my math classes. I gave up. But now...with youtube and Google...i realized math is incredibly beautiful and filled with patterns and proofs. I now understand WHY the hypotenuse is equal to the squares of the two sides. Thanks to you I understand how to find the square root in a way that makes sense. All the pieces are finally coming together. I am obsessed with mathematics now...and patterns. I am glad this generation has youtube and Google in a way. If they use it to understand it will greatly help.

this is honestly amazing and I love you. I wish you were my teacher for all 13 years of my schooling. in all subjects.

Welcome to the Square Root International Airlines!

the dislikes are from teachers who's mad because it isnt their way of solving

This guy is the goat... so good

The fact that I have learning disability and learn this is amazing

Next time my teacher says there is no way to accurately calculate a square root I’ll be sitting in the back of the class smirking and not saying anything bc I’m to shy

another little trick, you dont really need to memorize the square roots.. the last numbers have a ladder pattern.. up then down kinda thing.. 1 pairs with 9, 2 with 8, 3 with 7, 4 with 6, and 5 is alone

Very good...I learned it within seconds here and I never knew how to solve it when I was in school....very good

My teacher asked are you using a calculator near me. Thx man you changed my square problem

WOW a video from 5 years ago is teaching me faster and easier than my own advanced math teacher 😭

This trick works given that the number is a perfect square. Otherwise, it provides a very close estimate. Very nice.

Nice video tecmath!

A friend of mine showed me this in high school, and I couldn't follow the steps. That is still true. I concluded that the only way i have to find the square root of any number in 3 seconds is to type the number in the calculator and press the square root button. That is also still true.

*Me finds square root in 4 seconds Me: LIAR!

I put the video in 2x speed so now I can square root in 1.5 seconds

Found this for my sister. Why couldnt I have found it when I was in school?! This makes Math so much easier! Great video!

I searched RU-vid for many easy tricks for roots by far this is the easiest 👍

I wish you were my math teacher when I was in school. I would have been a very different person

I can't wait to put this skill into practice and make my math teacher jelaous

Damn I learned it in 5 mins Fam Thanks

AAAAA thank youuuu although im 11 and very bad at math this made me understand so much better:D my teachers make it boring you saved me now i dont need a calculator:)))) much thanks from a 6 grader i will appreciate this:DDD

Australian Bob Ross. listen to that voice :D

Why don't teachers explain as good as him

This video deserves more likes so simple sp calm good examples

This is very helpful for my exams as now I can easily do square roots in seconds than doing trial and error, Thanks.

Funny how I took a 72 question test today and I’m watching this now. RU-vid algorithm is the best.

Teachers : Report this video please, it is making the kid having fun with homework.

Thats an amazing trick. Thanks a lot

I was absent from school today because I am sick, and this is gonna be useful tomorrow for the quiz we took in class.

I found this video sooo many years later. You are a legenddddd. You cleared my confusion of 4 years in 10 minutes AHHHHH

You can do it less than 3 seconds, just memorize the square root table up to infinity, which is the number you stipulate yourself.

omg why am I just finding out about this channel...this was great!

Loved every minute of it.!! Thank you.
